Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a door body assembly and a refrigeration device. Background Art

[0002] With the increasing demand for the integration of household appliances and home furnishings, the embedded design of household appliances has become a trend. Most refrigerators on the market currently use single-axis or double-axis hinges to achieve the rotational connection between the refrigerator door and the refrigerator body. This design is mainly to meet the embedding requirements of the refrigerator, ensuring that the refrigerator door does not exceed the side of the refrigerator during the process of opening and closing the door, thus avoiding interference with the side cabinet wood boards.

[0003] However, in order to pursue a better home integration effect, sometimes it is necessary to fixedly connect a door panel to the surface of the cabinet door. Although this design can reduce the integration degree of the appliance and the home, it also increases the thickness of the entire door body assembly. This results in that after the appliance is pushed into the cavity, relying solely on the original single-axis or double-axis hinge, the door body assembly with the door panel may interfere with the side of the installation space body during the process of opening and closing the door, thus causing the door body assembly of the appliance to be unable to be opened or closed normally. Summary of the Utility Model

[0004] The utility model aims to at least solve one of the technical problems existing in the related art. For this reason, this application proposes a door body assembly to solve the problem that the door body assembly with a door panel may interfere with the side of the installation space body during the process of opening and closing the door, resulting in the door body assembly of the appliance being unable to be opened or closed normally.

[0005] The utility model also proposes a refrigeration device.

[0010] According to the door body assembly of the embodiment of the utility model, when the user has the demand to open the door body assembly, the door body assembly is moved to rotate outward relative to the electrical appliance body. During the rotation of the door body assembly, the pressure inside the pump body is controlled to rise.

When the equipment installed with the door body assembly is embedded, the door panel always avoids the walls on both sides of the width direction of the door body assembly during the opening of the door body assembly. Similarly, when the user closes the door body assembly, the internal pressure of the pump body is controlled to decrease, so that the overall volume of the pump body and the transmission member is reduced, causing the second end of the transmission member to move toward the pump body to drive the door panel to reset.

[0043] The following Figures 1 to 3 describes the door body assembly and refrigeration equipment of the present application. The door body assembly in the present application can be applied to household appliances, such as refrigerators. However, it should be understood that the door body assembly in the present application can also be applied to dishwashers, washing machines, or any other suitable equipment. The refrigeration equipment in the present application is applied as a refrigerator, for example. However, it should be understood that the refrigeration equipment in the present application can also be applied to freezers or any other suitable equipment.

[0044] Combined with Figure 1 and Figure 2As shown, the door body assembly according to the embodiment of the first aspect of the utility model includes a cabinet door 10, a door panel 30 and a transmission mechanism 40; the cabinet door 10 is rotatably connected to the electrical appliance body 20, and is suitable for opening or closing the storage space of the electrical appliance body 20; the door panel 30 is slidably arranged on the outside of the cabinet door 10; the transmission mechanism 40 includes a pump body 41 and a transmission member 42, a first end of the transmission member 42 is sealed and connected to the pump body 41, and a second end can move relative to the pump body 41, the transmission mechanism 40 is arranged on one of the cabinet door 10 or the door panel 30, and the second end of the transmission member 42 is connected to the other, and the transmission mechanism 40 is suitable for controlling the movement of the second end of the transmission member 42 through the pressure change of the pump body 41, so as to realize the relative sliding of the door panel 30 and the cabinet door 10.

[0045] According to the door body assembly of the first embodiment of the utility model, when the user needs to open the door body assembly, the door body assembly is moved to rotate outward relative to the electrical appliance main body 20. During the rotation of the door body assembly, the internal pressure of the pump body 41 is controlled to rise. Since the volume of the pump body 41 remains unchanged, the excess pressure in the pump body 41 needs to be moved through the second end of the transmission member 42 to balance it by changing the overall volume of the pump body 41 and the transmission member 42. At this time, the second end of the transmission member 42 drives the door panel 30 to slide relative to the cabinet door 10. When the equipment installed on the door body assembly is embedded, during the opening of the door body assembly, the door panel 30 always avoids the walls on both sides of the width direction of the door body assembly. When the user closes the door body assembly, similarly, by controlling the internal pressure of the pump body 41 to decrease, the overall volume of the pump body 41 and the transmission member 42 is reduced, causing the second end of the transmission member 42 to move toward the pump body 41 to drive the door panel 30 to reset.

[0046] According to the door body assembly of the embodiment of the utility model, a pump body 41 is provided to drive the transmission member 42 to drive the door panel 30 to slide relative to the cabinet door 10, so that the door panel 30 assembly can be staggered from the side wall during opening and closing, thereby avoiding interference between the door panel 30 and the outside when the cabinet door 10 rotates, and can meet the user's usage requirements in different scenarios; and when the door panel 30 assembly is in the closed state, the cabinet door 10 and the electrical body 20 are hidden on the side of the door panel 30 away from the user, effectively improving the aesthetics.

[0047] In this embodiment, the transmission mechanism 40 is arranged on the box door 10, and the second end of the transmission member 42 is connected to the door panel 30, which is conducive to the connection between the pump body 41 of the transmission mechanism 40 and the power supply line or control line in the box door 10; of course, the transmission mechanism 40 can also be arranged on the door panel 30, and the second end of the transmission member 42 is connected to the box door 10 to realize the relative sliding of the driving box door 10 and the door panel 30.

[0048] In this embodiment, the pump body 41 can be an airbag pump, and gas can be filled into the pump body 41 to change the internal pressure of the entire pump body 41 and the transmission member 42; of course, based on different media (such as water), other types of pump bodies 41 can also be used.

[0049] In this embodiment, controlling the pressure of the pump body 41 can be achieved by using a control button. For example, the user presses the control button to control the increase or decrease of the pressure of the pump body 41; it can also be in the form of setting a sensor 70 to automatically detect whether the door body assembly moves relative to the electrical appliance body to automatically control the pressure of the pump body 41.

[0050] According to an embodiment of the present invention, in combination with Figure 1 and Figure 2 As shown, the transmission member 42 includes a translation rod 421 and a first multi-section hollow push rod 422; the pump body 41 includes a door-opening pump 411. The first end of the first multi-section hollow push rod 422 is hermetically connected to the door-opening pump 411, and the second end of the first multi-section hollow push rod 422 abuts against the first side of the translation rod 421.

[0051] In this embodiment, the first multi-section hollow push rod 422 is a multi-layer sleeve structure extending along the moving direction of the translation rod 421. When the door body assembly covers the electrical appliance body, the multi-layer sleeves of the first multi-section hollow push rod 422 are nested, so that the translation rod 421 connected to the first multi-section hollow push rod 422 approaches the pump body 41, and the door panel 30 shields the box door 10. When the user opens the door panel 30 assembly, the pressure inside the pump body 41 rises. The multi-layer sleeves of the first multi-section hollow push rod 422 are misaligned, so that the overall volume of the first multi-section hollow push rod 422 and the pump body 41 increases to balance the pressure. Correspondingly, the translation rod 421 connected to the second end of the first multi-section hollow push rod 422 moves away from the pump body 41, thereby driving the door panel 30 to slide outward relative to the box door 10.

[0052] By providing the translation rod 421 and the first multi-section hollow push rod 422, the first multi-section hollow push rod 422 can be telescopic without occupying the internal space of the pump body 41. Furthermore, a smaller pump body 41 can be used, reducing the volume of the door body assembly.

[0053] In other embodiments, the first multi-section hollow push rod 422 can also be replaced with a piston rod. Under the action of the internal pressure of the pump body 41, the piston rod moves relative to the pump body 41 as a whole to push the translation rod 421.

[0054] In this embodiment, the first multi-section hollow push rod 422 and the translation rod 421 are integrally formed to ensure the sealing between the two and prevent the medium in the pump body 41 from leaking.

[0055] In one embodiment, in combination with Figure 1 and Figure 2As shown, the transmission mechanism 40 further includes a reset member 43. The first end of the reset member 43 is fixed relative to the door opening pump 411, and the second end is connected to the translation rod 421, and is adapted to drive the translation rod 421 to reset in the contraction direction of the first multi-section hollow push rod 422.

[0056] In this embodiment, the reset member 43 can always provide a certain pushing force to the translation rod 421 (i.e., the force from left to right in FIG. 1). If it is in the form of an elastic member, when the pushing forces provided by the right door opening pump 411 and the first multi-section hollow push rod 422 cannot overcome the pushing force of the reset member 43, under the action of the reset member 43, the translation rod 421 will move towards the door opening pump 411, and the corresponding door panel 30 will reset relative to the box door 10.

[0057] Of course, the reset member 43 can also be a way of providing a pushing force only when the door body assembly has a tendency to close relative to the electrical appliance main body 20. For example, a pump body 41 or a cylinder body is provided on the side of the translation rod 421 away from the door opening pump 411 to push the translation rod 421.

[0058] According to an embodiment of the present invention, in combination with Figure 1 and Figure 2 As shown, the reset member 43 includes a second multi-section hollow push rod 431 and a reset pump 412. The door opening pump 411 and the reset pump 412 are arranged on both sides of the translation rod 421. The first end of the second multi-section hollow push rod 431 is hermetically connected to the reset pump 412, and the second end of the second multi-section hollow push rod 431 abuts against the second side of the translation rod 421, and the second side is arranged opposite to the first side.

[0059] In this embodiment, taking the user closing the door panel 30 assembly as an example, the pressure inside the reset pump 412 is controlled to rise. Through the dislocation of the multi-layer sleeves of the second multi-section hollow push rod 431, the overall volume of the second multi-section hollow push rod 431 and the reset pump 412 increases to balance the pressure. Correspondingly, the translation rod 421 connected to the second end of the second multi-section hollow push rod 431 moves towards the door opening pump 411; while the pressure inside the door opening pump 411 decreases, the multi-layer sleeves of the first multi-section hollow push rod 422 are nested, so that the overall volume of the first multi-section hollow push rod 422 and the pump body 41 decreases to balance the pressure. Correspondingly, the translation rod 421 connected to the second end of the first multi-section hollow push rod 422 moves towards the door opening pump 411. Under the combined action of the reset pump 412 and the door opening pump 411, the translation rod 421 drives the door panel 30 to slide inwards relative to the box door 10. The same is true when the user opens the door body assembly, just in the reverse direction. By setting the reset pump 412 and the door opening pump 411, compared with using only the reset pump 412 or the door opening pump 411, the moving efficiency of the translation rod 421 is higher, effectively improving the moving efficiency of the door panel 30.

[0060] According to an embodiment of the present utility model, the transmission mechanism 40 further includes a first control valve 441 and a second control valve 442; the supply port of the external medium source 90 is communicated with the inlet of the door opening pump 411 to form a first inlet source pipeline 51, and the outlet of the door opening pump 411 is communicated with the return port of the external medium source 90 to form a first outlet source pipeline 52. The first control valve 441 is adapted to control the on / off of the first inlet source pipeline 51 and the first outlet source pipeline 52; the supply port of the external medium source 90 is communicated with the inlet of the reset pump 412 to form a second inlet source pipeline 53, and the outlet of the reset pump 412 is communicated with the return port of the external medium source 90 to form a second outlet source pipeline 54. The second control valve 442 is adapted to control the on / off of the second inlet source pipeline 53 and the second outlet source pipeline 54.

[0061] In this embodiment, when the user opens the door body assembly, the first control valve 441 controls the first inlet source pipeline 51 to be conducted, the first outlet source pipeline 52 to be closed, the second control valve 442 controls the second inlet source pipeline 53 to be closed, and the second outlet source pipeline 54 to be conducted. The medium inside the reset pump 412 flows back to the external medium source 90 through the second outlet source pipeline 54, and the pressure drops. The multi-layer sleeves of the second multi-section hollow push rod 431 are stacked, and the translation rod 421 connected to its second end moves away from the door opening pump 411; while the medium of the external medium source 90 enters the door opening pump 411 through the first inlet source pipeline 51, the internal pressure of the door opening pump 411 rises, the multi-layer sleeves of the first multi-section hollow push rod 422 are misaligned, and the translation rod 421 connected to the second end of the corresponding first multi-section hollow push rod 422 moves away from the door opening pump 411. Under the combined action of the reset pump 412 and the door opening pump 411, the translation rod 421 drives the door panel 30 to slide outward relative to the box door 10. Similarly, when the user closes the door body assembly, at this time, the first control valve 441 controls the first inlet source pipeline 51 to be closed, the first outlet source pipeline 52 to be conducted, the second control valve 442 controls the second inlet source pipeline 53 to be conducted, and the second outlet source pipeline 54 to be closed.

[0062] In this embodiment, by providing the first control valve 441 and the second control valve 442, the reset pump 412 and the door opening pump 411 can use the same external medium source 90, effectively improving the integration degree of the door body assembly and reducing the number of components.

[0063] In this embodiment, when the door opening pump 411 or the reset pump 412 adopts an airbag pump, the external medium source 90 can be air; when other types of pumps 41 are adopted, the type of the external medium source 90 can also be correspondingly replaced.

[0064] According to an embodiment of the present utility model, in combination with Figure 2As shown, along the moving direction of the translation rod 421, the first multi-section hollow push rod 422 and the second multi-section hollow push rod 431 are arranged in a staggered manner. This is to reduce the length of the transmission mechanism 40 along the moving direction of the translation rod 421, and correspondingly increase the thickness perpendicular to the moving direction, so as to adapt to the door body assembly with a smaller size along the moving direction of the translation rod 421.

[0065] According to an embodiment of the present invention, in combination with Figure 1 and Figure 2 As shown, the door body assembly further includes a sensor 70. The sensor 70 is adapted to detect the movement of the door body assembly relative to the electrical appliance main body 20. The sensor 70 is connected to the transmission mechanism 40 and controls the movement of the transmission mechanism 40 based on the movement state of the door body assembly relative to the electrical appliance main body 20.

[0066] In this embodiment, the movement detected by the sensor 70 can be transmitted to the pump body 41 of the transmission mechanism 40 in the form of a signal. For example, when the sensor 70 detects that the door body assembly is moving away from the electrical appliance main body 20, it can send a positive signal, and when it detects that the door body assembly is approaching the electrical appliance main body 20, it can send a negative signal. Here, the positive signal and the negative signal are not relative relationships, and only uniqueness is required to control the state of the pump body 41. For example, the positive signal can be a high-level signal, and the negative signal can be a low-level signal.

[0067] In a specific embodiment, when the user opens the door body assembly, the sensor 70 detects the movement of the door body assembly relative to the electrical appliance main body 20 and sends a positive signal. The transmission mechanism 40 controls the internal pressure of the pump body 41 based on the positive signal. For example, it controls the pressure of the reset pump 412 to decrease. The multi-layer sleeves of the second multi-section hollow push rod 431 are stacked, and the translation rod 421 connected to its second end moves away from the door pump 411; and it controls the internal pressure of the door opening pump 411 to increase. The multi-layer sleeves of the first multi-section hollow push rod 422 are misaligned, and the translation rod 421 connected to the second end of the corresponding first multi-section hollow push rod 422 moves away from the door pump 411. Under the combined action of the reset pump 412 and the door opening pump 411, the translation rod 421 drives the door panel 30 to slide outward relative to the box door 10. The same is true when the user closes the door body assembly. The sensor 70 generates a negative signal, and the transmission mechanism 40 controls the internal pressure of the pump body 41 based on the negative signal.

[0068] In this embodiment, the movement of the door body assembly relative to the electrical appliance main body 20 is automatically detected by the sensor 70 without user control, effectively improving the timeliness of the movement of the door panel 30 relative to the box door 10 and ensuring the safety of the movement of the door panel 30. And by changing the parameters of the transmission mechanism 40 (such as the unit input and output of the pump body 41, the length of the first multi-section hollow push rod 422, etc.), the movement speed of the door panel 30 relative to the box door 10 can be changed, effectively adapting to the requirements in different situations.

[0069] In this embodiment, the door body assembly may further include a main control board and a pre-buried wire (not shown in the figure). The main control board is connected to the sensor 70 and the transmission mechanism 40 through the pre-buried wire. The main control board may control the operation of the transmission mechanism 40 based on the positive or negative signal fed back by the sensor 70.

[0070] In this embodiment, the sensor 70 may be a distance sensor, which is fixed to the cabinet door 10 or the electrical appliance main body 20. During the opening and closing process of the door body assembly, the distance between the cabinet door 10 and the electrical appliance main body 20 changes to generate a signal. Of course, other types of sensors 70 may also be used, such as an angle sensor, a speed sensor, etc., which are suitable for detecting the change in physical quantity during the relative movement of the door body assembly and the electrical appliance main body 20 and generating a signal.

[0071] According to an embodiment of the present invention, in combination with Figure 1 and Figure 2 as shown, the translation rod 421 is provided with a slider 4221, and the door panel 30 or the cabinet door 10 is provided with a sliding groove 11 corresponding to the slider 4221.

[0072] In this embodiment, the sliding groove 11 is provided on the cabinet door 10. During the movement of the translation rod 421, the slider 4221 always moves along the sliding groove 11, effectively improving the stability of the movement of the translation rod 421. Of course, when the transmission mechanism 40 is provided on the door panel 30, the sliding groove 11 is opened on the door panel 30.

[0073] In another embodiment, the sliding groove 11 may also be provided on the translation rod 421, and the door panel 30 or the cabinet door 10 is provided with a slider 4221 corresponding to the sliding groove 11. Similarly, it is only necessary to ensure that the slider 4221 and the sliding groove 11 cooperate to achieve the movement stability of the translation rod 421.

[0074] According to an embodiment of the present invention, in combination with Figure 3 as shown, a guiding portion 60 extending along the relative movement direction of the door panel 30 and the cabinet door 10 is provided between the door panel 30 and the cabinet door 10. The guiding portion 60 is suitable for supporting the door panel 30.

[0075] The guiding portion 60 may include a guiding base and a guiding slider. The guiding base is provided on the cabinet door 10, a guide rail is formed on the guiding base, and the guiding slider is slidably arranged on the guide rail. The guiding slider is connected to the door panel 30.

[0076] Among them, the guiding slider is connected to the door panel 30, and this connection method can be selected according to actual needs, such as by screws, welding, buckles, etc. Through this connection method, when the door panel 30 and the cabinet door 10 slide relative to each other, the door panel 30 can push the guiding slider to slide on the guide rail, which can greatly increase the stability during the relative sliding process of the door panel 30 and the cabinet door 10.

[0077] In addition, by designing the guide rail, for example, by providing a limit structure at the end of the guide rail, the moving distance of the door panel 30 can also be adjusted according to actual needs to meet the needs of different users.

[0078] In this embodiment, three of the four corners of the door body assembly are provided with guiding portions 60, and the remaining one corner is provided with a transmission mechanism 40. Of course, the number of the guiding portions 60 can be adjusted accordingly based on requirements such as the weight of the door panel 30 and the sliding stability between the door panel 30 and the cabinet door 10.

[0079] According to an embodiment of the present invention, the transmission mechanism 40 is disposed at the top of the door panel 30 or the cabinet door 10, which is convenient for the staff to repair and replace the components of the transmission mechanism 40, and improves the maintenance and installation efficiency.

[0080] The refrigeration device according to the second aspect embodiment of the present invention is the above-mentioned door body assembly.

[0081] The refrigeration device according to the embodiment of the present application has the same beneficial effects as the door body assembly of the first aspect embodiment of the present application, and will not be elaborated herein.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
